推荐答案
使用Linq
Use Linq
lv3.Items.Add(lv2.Items.Except(lv1.Items).Union(lv1.Items.Except(lv2.Items)))
从Listview2中逐一删除项目.
在ListView1中搜索.
如果找不到,则将其添加到Listview3中.
这是什么问题?
Take one by one items from Listview2.
Search it in ListView1.
If not found then add that item in Listview3.
What is the problem in this?
